Hope in a Test
Tube - A new website gives patients a chance to join
drug tests for everything from autism to sickle-cell anemia
By Jyoti Thottam
Most of the time, Kelly Scott doesn't worry much about her daughter
Bailey, an energetic 10-year-old who loves to ski near her family's
home in Maine. But once a year, Scott remembers the day when
Bailey, then a week old, had surgery to reverse the position
of the two largest arteries in her heart. Bailey was part of
a clinical trial at Children's Hospital Boston, and annual check-ups
let researchers track her progress. Scott found out about the
trial in the usual way her doctors told her about it.
"They didn't give us many choices," she says. "It
didn't seem that there were any."
Today, things are different. When Scott wanted to know how Bailey
was doing compared with other children in the study information
her doctor was reluctant to share she went to ClinicalTrials.gov
, a database launched last year by the National Institutes of
Health (NIH). Although it was difficult for her to read mortality
statistics about children who began life just as Bailey did,
Scott says, "I would rather know."
ClinicalTrials.gov, an ambitious scheme funded by the federal
government, could open the world of drug trials a byzantine
network of research hospitals, drug companies, private physicians
and government agencies to the public. Alexa McCray,
the project's director, predicts that it will fundamentally
change the doctor-patient relationship. "My hope is that
it will be more of a partnership," she says, once patients
know more about their treatment options. Whether or not McCray
succeeds will depend on drug companies' willingness to share
jealously guarded research and patients' readiness to take a
more active role in their own treatment.
Until now, lack of access to information about drug studies
has kept people from enrolling and possibly getting the help
they need. "Only about 3% of adults with cancer participate
in clinical trials," says Dr. Ted Gansler, medical editor
for patient information at the American Cancer Society. "That
number should be at least 10%." In 1997, though, the Food
and Drug Administration Modernization Act was passed in response
to lobbying by patients' rights groups; this act calls on the
government to build a database of clinical trials that will
tell patients who is eligible for a given trial and which institution
sponsors it. The law says nothing about the Web, but McCray
and her staff at the National Library of Medicine, an arm of
the NIH, chose a broad interpretation and went to the Net.
So far, ClinicalTrials.gov includes 5,200 listings of studies
seeking treatments for everything from autism to sickle-cell
anemia, and about 5,000 people check the free site every day.
Patients can search by condition, location and age group to
find trials for which they may be eligible, and they do not
need to submit any information about themselves. Most of the
listed trials are sponsored by the 21 research centers of the
NIH, but there are also some from drug companies, teaching hospitals
and private foundations.
To become truly comprehensive, however, ClinicalTrials.gov
will need greater cooperation from private drug companies. McCray
estimates that their research could triple the number of trials
in the database, but so far the pharmaceutical industry has
been unwilling to sacrifice proprietary information for the
sake of patient access. "Even the name of the study and
the hypothesis and the name of the investigator that
pretty much tells everybody else in the industry what you're
doing," says Larry Hirsch, a spokesman for Merck Research
Labs.
Drug companies simply have nothing to gain from ClinicalTrials.gov
, according to Nancy Roth, director of clinical strategic planning
and operations for Bristol-Myers Squibb. Unlike the NIH, which
relies on doctor referrals and self-referrals to recruit subjects,
drug manufacturers have the money to reach patients through
advertising or directly through doctors. McCray, the FDA and
the drug industry are trying to hammer out a compromise that
would allow companies to reveal limited information about their
tests. Ideally, McCray says, drugmakers would submit data for
ClinicalTrials.gov along with new drug applications to the FDA.
But so far, the industry has insisted that the law requires
such data to be submitted only for "serious or life-threatening
illnesses," such as cancer or AIDS.
ClinicalTrials.gov is not the only resource for patients who
need such help. TrialsCentral , a nonprofit effort, includes
dozens of links to other trial listings. The for-profit group
CenterWatch runs a site to which companies voluntarily
submit information, so the listings often do not include details
about the drug or its sponsor. Myrl Weinberg, president of the
National Health Council, a coalition of 50 patient-advocacy
groups, says she hopes the NIH will take CenterWatch's
example. If asking for proprietary information prevents drug
companies from giving any data at all, Weinberg says, "we
would support not asking for it."
Regardless of how successful ClinicalTrials.gov proves to be,
patients can no longer afford to ignore online information about
clinical trials doctors actually expect them to be informed.
"Patients have much more time than we do to search for
things," says Dr. Jeffrey Raizer, attending neurologist
at Memorial Sloan-Kettering Cancer Center in New York City.
Even if they have the information, doctors may be reluctant
to enroll patients in a trial unless they have exhausted other
treatment options or the patient makes a specific request. "It's
a lot of work for the doctor," says Dr. Barry Kaplan, director
of medical oncology at New York Hospital Medical Center of Queens.
"Why would he want to do it?"
Perhaps because a clinical trial can be a patient's only hope.
ClinicalTrials.gov may not be a perfect solution: even Dr. John
Gallin, director of the NIH Clinical Center, says that depending
on the Web to disseminate medical information denies access
to more than half of the U.S. population and to two-thirds of
African-Americans (who are already underrepresented in clinical
trials). Nevertheless, putting this vital information in one
central place could be an important first step.
